Study Notes

Foreground vs. Background Questions

Foreground questions are specific and aim to identify the effect of a particular intervention.
Background questions are general and provide broad knowledge about a topic.
Foreground questions utilize the P.I.C.O. framework (Patient, Intervention, Comparison, Outcome) for precision.
Background questions involve inquiries like who, what, where, when, and how.

The PICO Process

PICO helps clarify the single most important issue from the patient's perspective.
It assists in defining language and key terms for online searches.
PICO focuses on identifying specific problems and expected outcomes.
Helps determine the types of evidence needed for effective interventions.

Qualitative/Descriptive Primary Research

Qualitative research complements quantitative research by providing context and understanding the underlying reasons.
Ethnography examines group cultures through observation and interviews.
Phenomenology focuses on personal experiences via in-depth interviews, anecdotes, and artistic expressions.
Grounded theory emphasizes theory development from natural interactions.

Potential Biases in Clinical Research

Recall bias: Impacts self-reported data accuracy, common in retrospective studies.
Selection bias: Occurs in non-randomized group assignments, affecting observational study validity.
Investigator bias: Researchers' influences can skew outcomes in qualitative designs.
Placebo bias: Participants’ perceptions of treatment effects can alter study results.

Role of the Researcher

In quantitative research, the researcher remains detached from the subject.
In qualitative research, the researcher is deeply involved and interacts with the subject matter.

Quantitative/Analytical Secondary Research

Secondary research primarily comprises synthesized publications of primary research.
Systematic reviews and meta-analyses summarize findings from multiple studies on specific questions.
Over 2 million articles are published annually, making systematic reviews essential for information synthesis.

Systematic Reviews vs. Traditional Narrative Reviews

Systematic reviews have a narrow focus on specific patient problems and pre-established inclusion criteria.
Traditional narrative reviews have a broader scope and may lack strict criteria.
Systematic reviews minimize bias and report findings in a structured format.

Finding Evidence: Resources

Cochrane Database of Systematic Review offers full-text systematic reviews and protocols.
DARE provides abstracts of effectiveness reviews.
The Cochrane Central Register lists controlled trials.
CINAHL contains evidence relevant to nursing and allied health fields.
PubMed Clinical Queries supports evidence-based search methodologies.

Boolean Operators for Searching

AND: Narrows searches by requiring both terms.
OR: Broadens searches by including either term.
NOT: Excludes terms, refining search results.
Using parentheses prioritizes information within them during searches.

Levels of Evidence

Evidence is ranked to reduce bias and enhance reliability in patient care decisions.
Randomized Controlled Trials (RCTs) offer stronger evidence than cohort or case-control studies.
The "Evidence Pyramid" illustrates the hierarchy of evidence quality, with higher levels providing more reliable answers to clinical questions.
